I am curious as I was just given a 9.7" ipad pro wifi, 32 gig for my birthday. As stated in the title of the question, when i think of silicone, I think of it as an extremely flexible material with very little rigidity. That is was also prone to stretching out in a short amount of time.

Mikael S's answer on April 25 is not correct, based on the case I purchased. The case he got must have a manufacturing defect; i.e., the punch out must not have been completed properly or something. The case has holes that line up perfectly with all 4 speakers. However, to be honest, even with that I can tell a slight difference in the sound - there is some diffifusion and muting. Any case is going to have that effecting unless they have a complete cut-out for the speakers.

An apple pro case and cover were purchased for me through my work and the rubber of the case is crumbling off on the corners. Since i have only had it for a couple months I'm wondering if I can exchange it for a new one as this one must be defective.
